Landesman is adapting the screenplay. The film, to be shot in Austin, Texas, is being planned for a 2013 U.S. theatrical release to coincide with the 50th anniversary of the assassination.

“Tom Hanks and Gary Goetzman are two exceptional producers with great taste so we are delighted to be collaborating with them on this fascinating film about such a significant chapter in American history,” Sinclair and East. “Paul, Billy Bob and Jacki are perfectly cast to bring Vincent’s book to life.”

Exclusive Media’s Matt Jackson will oversee the production on behalf of the company and Exclusive Media will handle the worldwide distribution rights to the movie, which will be introduced to buyers at the American Film Market.
